X-13ARIMA-SEATS Compatibility with 32-bit Windows

Question:

Why can’t I run the X-13ARIMA-SEATS function on my 32-bit windows machine?

Answer:

NumXL is using the Windows version of U.S. census seasonal adjustment software behind the scenes.

As of June 2020, the U.S. census has discontinued delivering a 32-bit version of their program.

https://www.census.gov/data/software/x13as/x13as-archive/release-notes-v11-b57.html

What does this mean?

For users running the 32-bit version of Microsoft Windows OS, the U.S. census X-13ARIMA-SEATS software is incompatible with the version of the OS and NumXL can’t invoke the program. Users are urged to upgrade their Windows OS or use the X12-ARIMA legacy seasonal adjustment function.

What about the 32-bit version of Excel?

For the 32-bit version of Microsoft Excel installed on a 64-bit version Windows system, NumXL supports the X-13ARIMA-SEATS seasonal adjustment function.
